IOGEAR GPU202 Hi-Speed USB 2.0 CardBus – Support Forum

I have on order the IOGEAR Hi-Speed USB 2.0 Cardbus adaptor, but it is not available at present. Would D-Link DUB-C2 2-Port USB 2.0 Cardbus Adaptor (£20.95) do the job as well. The job being to add USB2 to my Powerbook G4 through PC cardbus 11 port.
Thanks
